We announce the release of new service named Formula,
which provides a way of embedding mathematical equations into your blogs and sharing it.

http://formula.s21g.com/

Using the service, everybody can easily bring a beautiful mathematical expression to a blog post, like this.

You can jump to the page of discussion about the expression by clicking the image of the expression.

Usage is quite simple.

1. Write a mathematical expression in LaTeX format into the form in the top page of Formula.
2. And then, you will get the image of the expression at the bottom of the form as a preview.
3. Finally, you can generate the HTML snippet of the image
   for embedding by clicking the Submit button.

There is no need to sign up to use this service.

For details, email us to .
We appreciate any kind of feedbacks.

Thank you.

I am using Skype Chat everywhere because it is useful.
But it has a limit due to its P2P mechanism that is needing at least 2 online users in order to keep messages transmitted completely.

When you are the only online user in the chat room, the messages sent by you are stored locally until someone comes in.
In other words, suppose the chat room has user A and B;

1. A said hello to B.
2. A had logged out and became offline.
3. "hello" had been stored into A's PC.
4. B has become online.
5. Nothing happen.

To solve this problem, I have been running the SkypeBot upon my Mac mini server and made it join to the chat rooms with me.
By this, the chat room can always have over 2 online users so that all messages can be sent to each other.

Thus, I provide the SkypeBot identified by 'skype.s21g' which is always online except when I update Mac mini.
Everyone can use this by dropping it into your open Skype chat which has no problem about privacy.

Now, we are working on ShootingStar-4.0.0

It will be working on Windows by using WaitForMultipleObject API.
I loved it since more than 10 years ago and thought it as is one of a beautiful aspect of Windows.

It may be shipped on next month.
